  • Tape measure
  • Carpenter’s level
  • Circular saw
  • Hammer
  • Nail Gun
  • Lumber

How to Build a Freestanding Double Door Frame  Easy Steps

Freestanding double door (AKA French doors) framing is a relatively straightforward process that is accomplished in just a few steps. Here’s a step-by-step guide on how to do it:

Step 01. Measure the Opening:

One of the most critical aspects of building a freestanding double door frame is measuring the opening correctly with a tape measure. The process is relatively simple, but there are a few things to keep in mind. Measure the opening from the bottom of the entrance to the top and from left to right.

If there are two doors, measure the door that will be on hinges. You should measure the door height from the floor to the underside of the header. For door width, measure from stud to stud on the frame where you plan to hang the door.

Most door openings are 6 feet 8 inches high and 3 feet wide (sizes can be customized). But it is essential to measure your specific door opening before purchasing or building your doors. The doors should be spaced 1/4 inch apart when closed to prevent sticking.

Step 02. Cut the Lumber:

When DIYing a self-standing double door frame, it’s essential to cut the lumber correctly so that the door will fit snugly and securely in the opening. To start, you’ll need two side posts, a top post, two base frames, and a base frame connector. The side posts and base frame should be cut to the same height.

Two 4×4″ side posts must be cut to the desired height of the frame, and one 4×4″ top piece should be cut to fit between the two side posts with a circular saw. Two 4 feet 2×4″ frame pieces need to be cut to length, and one 2×1″ 6 feet base connect piece is required to attach the two base frame pieces at the center.

Step 03. Assemble the Base frame:

When you are ready to start building your independently standing double door frame, you first need to put together the base frame. To do this, take your two base frame pieces and your base connect piece. Center the base connect piece on top of the base frames and screw it into place with 3″ plywood screws creating an H-shape frame.

Remember to pre-drill your holes to avoid splitting the plywood. Once the base frame is together, set it aside until time to attach the side posts.

Step 04. Attach the Side Frame:

Assemble the Base frame

The side frames are the main support structure for the double door because the door panel will be mounted on these frames. You should use brackets of 12 inches to ensure the side frames are securely attached to the base frame.

Place the side posts in the center of the base frames so that their tops are level. Then, mark the hole position for the bracket on both the side post and the base frame. With a drill, make a pilot hole at each mark, and then use screws to attach the bracket.

Make sure the frame is level with a carpenter’s level before attaching the other side. Repeat this process for the other side. It is necessary to attach the header to both side frames. A construction adhesive can secure the joint between the main and side posts.

Step 05. Install the Header Post

The header post is the horizontal piece of plywood that goes across the top of the door frame. It is usually made out of 2×4″ lumber. The header is installed after the top plate, and the studs have been put in place. With large T braces, the header is attached to the studs with nails or screws.

The size of the header depends on the width of the door frame. Wider doors require a bigger header. A header must also be strong enough to support the weight of the doors. A double door frame might need a bigger header than a single door frame.

It is possible to install the header before or after the doors are hung. If you are hanging the doors yourself, it is easier to install the header first.

Step 06. Attach Door Panels:

The door panels must be attached to complete the construction of your freestanding double door frame. Upon installation of the door panels, the hinges will be mounted. Before securing the hinges, ensure that the door panels are flush with the frame. Align the door panels with the door frame’s top and bottom rails.

Also, the door hinges should be attached to the door panel at the top and bottom. There should be at least two screws per door hinge. Ensure that the screws are long enough to pass through the door panel and into the door frame.

After the door hinges have been attached, the door handles can be attached. To allow the doors to swing freely, provide adequate clearance around the frame’s edges.

Follow these steps to build a standalone double door frame. By following this guide, you should be able to construct a sturdy and durable free standing door frame for your double doors.

The Secrets for a Sturdy Freestanding Double Door Frame Build

The Secrets for a Sturdy Freestanding Double Door Frame Build

The building process of a self-standing double door frame can be challenging, but there are a few tips and tricks that can make the process easier:

01. Build the Frame on a Stable and Level Surface

Any time you’re working with lumber, a key consideration is a surface you’re building on. It needs to be level, so your frame is level when you put it together. It also needs to be stable so the frame doesn’t wobble or shift while you’re working on it.

The best way to ensure a level and the stable surface is to build the frame on a solid concrete slab. If you don’t have access to a concrete slab, you can also use a level ground surface like a driveway or patio. Make sure that whatever surface you use is clean and smooth, so the frame goes together quickly.

02. Keep the Frame Together with Clamps

Building a frame that is sturdy enough to support two doors can be challenging. The key is to use clamps to keep the structure together while you work. With the help of clamps, you will be able to build a strong and stable frame.

Clamps will ensure that the frame is square and even, preventing the doors from sagging. It is also vital to use clamps when attaching the cross pieces to the frame, as this will help to keep the frame from twisting. Also, clamps can be used to attach the door hinges to the frame, ensuring that they are level and evenly spaced.

03. Use Treated Lumber if Possible

Any successful woodworking project starts with choosing the suitable lumber. For a freestanding double door frame, you’ll need solid and stable lumber. It’s crucial that lumber is treated for outdoor use.

Treated lumber is specially formulated to resist rot and decay, making it an ideal choice for outdoor DIY projects. Also, treated lumber is often more robust and durable than regular lumber, which will better withstand the components.

While it may be more expensive up front, using treated lumber will save you time and money in the long run. Untreated lumber will quickly rot and warp when exposed to the elements, so be sure to purchase lumber that has been treated with a weather-resistant coating.

04. Seal the Doors with Caulk and Weatherstripping

One of the essential points is sealing doors properly and weatherstripping them. In this way, you can prevent drafts and keep the doors from rattling in their frame. This will also help to prevent cold air from entering in the winter and hot air from escaping in the summer. Also, it will help to reduce noise pollution from outside.

05. Hang the Doors Using Heavy-Duty Hinges

Correctly hanging the doors is one of the key aspects of any standalone double door frame build. Heavy-duty hinges are a must, as they will provide the support needed to keep the doors in place. If they’re not, the door will eventually fall off, which could cause serious injury.

Also, it is significant to ensure that the hinges are correctly aligned. If the doors are not level, they will not close properly and could potentially cause damage to the frame. An easy way to do this is to use a carpenter’s leveler.

If the door isn’t level, it will cause the frame to warp over time, making it difficult to open and close. Even if the door isn’t aligned, it will put undue stress on the hinges, which could cause them to break over time.
